Not the greatest experience everything was pretty mediocre. My seat was by the washroom in the aisle and was not located well as everyone past each other people were right in my seat and space.

The small prop plane was crowded and the overhead luggage storage is a smaller than on the jets. Other than that, the crew was good, the flight was on time and the landing was smooth.

There was a medical emergency that the crew handled very well. There was no “entertainment” of any sort-no movie/music/whatever. Food was typical of airlines: mediocre.

Late departure, so I missed connection in Detroit. But Delta gave me a great hotel & breakfast. Just sorry I could not get anything from my checked baggage.

Crew was friendly. Lost our luggage and told us it’d be in later in the evening of the day we returned. It was not. Still after 5 days have not received it.

Internet on both flights was sketchy. Thus in flight entertainment was non- existent on MN - Balrimote leg.

We never had an experience they canceled the flight and they did not offer us an alternative flight. I had to book one on my own expense. They offered us food voucher and we could not use them at the airport it kept saying not attached to an existing flight. The people at the counter were rude and cold and they did not care about our situation

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

Found the seats very crowded—too close together ! And waited a long time for our luggage All staff at both ends were excellent!!!

Flight cancelled and Kayak switched our return flight to a red eye. Ridiculous.

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .

I had a nice flight with free wifi. So I was able to message family members and stream music during my flight, which made the trip go by fast. I also enjoyed flying on there Airbus A220. The plane looked very new and it also got up to speed fast down the runway and didn't need much runway to get airborne.

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊

I paid for a comfort class seat and was seated in economy.

My plane was cancelled and had to be rebook for the evening was not happy.

The flight was cancelled and we had to rebook on Porter to make our cruise the next day. Air Canada has not compensated. We won’t be flying with them again. This is the second time this has happened. Also the return flight was delayed 2 hours who knows why.

Leg room was terrible and seats very narrow. Flight was also delayed.

The worst airline experience that I ever had in my life. The fare was cheap but boy do you pay for it when it comes to baggages, carry-ons, food on board and lack of available staff at check-in. Almost every other passenger on my flight had the same complaints and experience. We all bonded discussing our displeasure. My husband and I will definitely not be traveling with Flair Airlines. We'll take anyone else.

The most uncomfortable plane I ever fly on. The seats won't even recline a little. For a 5 hrs flight at night and tired it felt like torture

Seats in 1 res are dispersed all over the plane, even child was across

Personally, I will not use this fight again. The service is poor, you have to buy even water. They don't provide anything even sneak, you have to buy. They said Personally items for 7 kg. Then they use some measurements, if you have 7kg and if it's not getting inside of their measurements, you have to pay 80$ this is robbery. I will prefer other flight then this. I am désappointement taking this airplane.

It’s a shameful company. It ask as to go to counter to take the boarding pass, they simply send it by email, just to check the bags’ size in a smaller than normal template. DONT USE FLAIR! It will be more expensive than normal airlines at the end.

flight was okay, no wifi, no free drinks but worst of all they lost my son's bike for four days. Customer service was nonexistent - call a number that leaves you on perpetual hold, there's no baggage folks in the baggage claims area (in vancouver). we went up to international and nobody was at ticketing, went to domestic and they had us fill out a form. they could not tell us where the bag was. Anyway, highly recommend you drop an airtag for anything that's worth more than $500. My son's bike costs a lot more than that to replace; I was on pins and needles for four days.

The crew of this flight, specially the flight attendant in the front were the sweetest I’ve had in all my life, I genuinely hope they get a race or sum cuz of their efforts. It was just quite unsettling that the flight took so long to departure. It was supposed to leave at 10:35pm and we ended up taking off at 11:22pm…👎🏻👎🏻👎🏻

It’s bare bones but was on time so can’t complain.

Of all the countries I've flown to and airlines from around the world, I have never had such a dismissive an arrogant employee during boarding. After waiting in line for 20 minutes to board, I was sent to a second line for Passport verification. Natalie from Flair, repeatedly tried to scan my passport which didn't work for some reason but was too lazy to input my information manually. Bar code scanners aren't 100% reliable as we all know. She asked me my birthdate 3 times, made me wait to be the last person aboard and then smugly threatened me that my only bag could be charged for (same backpack I used as on my arrival as carry on). Natalie working in Ft. Lauderdale and the was the epitome of lobotomized tiktok brain with the charm of junk mail.
